Embodiment Construction

[0072] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0073] like figure 1 As shown, the image deduplication system of the present invention includes a processing module 1, a repeatability calculation module 2, a judgment module 3, a deduplication module 4 and a pixel value calculation module 5;

[0074] Wherein, the pixel value calculation module 5 first calculates the pixel values ​​of the two images, and judges whether the pixel values ​​of the two images are the same, if so, it means that the two images are completely the same, and then from the two images One image is randomly removed, that is, the deduplication of two identical images is realized, and no follow-up operation is performed; if not, the processing module 1 is called.

[0075] The processing module 1 performs grayscale processing on the two images, and uniformly scales the two images to a standard size accordin...

Abstract

The invention discloses an image replication removing method and an image replication removing system. The image replication removing method comprises the following steps of S1, performing gray scale processing on two images, and zooming the two images to a standard dimension according to an initial width-to-height ratio; S2, calculating a repetition degree between the two images by means of a local two-value characteristic of the image; S3, determining whether the two images are repeated, if yes, performing a step S4; and S4, comparing qualities of the two images, and removing the image with low quality. According to the image replication removing method and the image replication removing system, local information and global information of the image are combined for performing repeated image determining so that advantage complementing is realized between different kinds of image information, thereby better ensuring high image replication removing speed, high replication removing effect and high completeness.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image deduplication method and system. Background technique [0002] Images contain rich and intuitive information. At present, in the fields of social networking, shopping, and tourism on the Internet, a large number of images are needed to convey information to users. As the number of images continues to increase, the number of repeated images is also increasing. Therefore, before using the image information, the provider of the image information needs to deduplicate the image to avoid repeated images, which will affect the user experience and increase the amount of maintenance of its own images. With the rapid development of the Internet, image providers use many channels such as user uploads and crawler downloads to obtain a large amount of image information every day, and the amount has far exceeded the limit of manual review. Therefore, it has become an urgent need to u...
